Compared with MZWLW15THGLA-00007, the Samsung PM1733 MZWLR15THALA-00AD3 delivers a clear generational step forward by moving to PCIe Gen4 x4 and scaling performance to 7,000/3,800 MB/s with up to 1,450,000/115,000 IOPS, enabling higher bandwidth and transaction density in the same 15.36 TB class. Its 28,032 TBW endurance, 1 DWPD rating, and Samsung V-NAND 3D TLC make it a strong fit for virtualized infrastructure, large-scale analytics, and read-intensive cloud storage tiers that need enterprise durability without sacrificing capacity efficiency.
With an endurance rating of 28,032 TBW and 1 DWPD, the MZWLR15THALA-00AD3 is built to handle very heavy write activity over its service life, far beyond the needs of typical OS, application, and mainstream server workloads. In practical terms, for common boot, database, virtualization, or mixed enterprise use, this level of endurance provides strong long-term headroom and can support years of stable operation with confidence. For enterprise reliability, this SSD includes power loss protection (PLP), which helps preserve data in flight and protects metadata integrity if power is unexpectedly interrupted. Its UBER of 1.0E-17, together with a 2 million hour MTBF, indicates an enterprise-class design focused on very low uncorrectable error rates and dependable continuous operation in business-critical environments.
1. The PCIe Gen4 x4 interface gives this drive the bandwidth headroom to keep multi-core servers and virtualization hosts fed without the storage link becoming the bottleneck.
2. Its 7000 MB/s sequential read performance accelerates large-block workloads such as AI model loading, data lake scans, and backup restore operations.
3. With 1,450,000K random read IOPS, it sustains extremely high small-block transaction rates, making it well suited for dense OLTP databases and latency-sensitive cloud applications.
4. A 1 DWPD endurance rating, backed by Samsung V-NAND 3D TLC, provides a balanced write-life profile for enterprise deployments that need predictable reliability under continuous daily use.
5. The 100 µs typical latency helps deliver faster application response times and tighter QoS consistency for real-time analytics, search, and high-concurrency VM environments.
Lower capacity reference: 7.68 TB Higher capacity reference: 30.72 TB In this SSD family, the 15.36 TB model is the sweet-spot capacity point. Compared with the 7.68 TB version, it gives much better headroom for data growth, denser server consolidation, and longer refresh cycles without changing the expected enterprise read/write and random IOPS profile. Compared with the 30.72 TB option, it typically delivers the best balance of acquisition cost, usable capacity, and predictable performance per drive. It is especially well suited for mid-scale virtualization clusters, analytics nodes, or high-density database storage in 2U servers.
Q: Is MZWLR15THALA-00AD3 suitable for a write-heavy database server?
A: Yes. With 1 DWPD, 28,032 TBW, PCIe Gen4 x4, and low 100 µs typical latency, it is suitable for mixed or moderate write-heavy database workloads in enterprise environments.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: It is rated for 1 DWPD, meaning it can sustain one full 15.36 TB drive write per day throughout its warranty period, aligned with its 28,032 TBW endurance specification.
Q: Does it include power loss protection (PLP) and why is that critical?
A: Yes, it includes PLP. This is critical because it helps protect in-flight data and metadata during sudden power failure, reducing corruption risk and improving reliability for enterprise applications.
Q: What RAID level is recommended for this SSD?
A: RAID 10 is commonly recommended for enterprise SSD deployments requiring strong performance and redundancy. RAID 1 or RAID 5 may also be considered, depending on capacity, protection, and rebuild priorities.
